The Arizona Cardinals added four players to the physically unable to perform list on Thursday due to injuries ahead of training camp. NFL Network's Ian Rapoport reported that the Cardinals placed the following players on the PUP list: tight end Tip Reiman, left tackle Paris Johnson Jr., cornerback Garrett Williams and outside linebacker Josh Sweat. Those are all losses of varying degrees for the Cardinals, so here's a breakdown of their impact and their injuries. Sweat, whose injury is undisclosed, will be a big loss for the Cardinals, however long he is out. Last season, Sweat tallied 12 tackles, four forced fumbles and 20 tackles.
